roush, paxton, whipple, my results,( yours may vary)
Over the past 12 months I have tried 3 different superchargers.
Not becasue I have an endless supply of money, but because I was never fully satisfied.
The roush with 8 psi made 382 hp and 339 torque
The Paxton at 10 psi made 439 hp and 380 torque
The paxton at 12 psi made 452 hp and 390 torque
The Whipple at 17 psi 482 hp 455 torque on a mustang dyno,
as a side note,, the same day it made 532 hp and 505 torque on a dynojet dyno. ( big difference between mustang dyno's and dynojet )
In the end I think the paxton was the best bang for the buck. it looks like if I had raised the boost on the paxton to 17 psi it would have beat the whipple, though the whipple makes more torque at lower rpm's.
All the Superchargers are good, and although My favorite was the paxton, your's may not be.
I liked the paxton because it was quiet, and MPG were the same as stock
(Both the roush and whipple lost several MPG )
it appears the roots style (Roush ) and twinscrew (Whipple )
Take more hp to turn than the centrifugal ( paxton ) .
But I am too lazy to change anything on the car for now, so I will stick with the whpple.
Just my 2 cents
Hope this helps someone.

However their are big differences between them.
I think the roush looks the cleanest on the car and was the easiest to install, but yielded the least power.
The paxton looks like a plumbers nightmare, and took the longest to set up.
And the whipple is very loud, ( to the point of annoying for everday driving) but gives the most torque.
so they all have their ups and downs.
like I said, these are just my observasions, yours may vary.

At 17psi, the whipple should make a LOT more power than that, even on the most conservative dyno. You need to find your air restriction and improve it. I've always found the whipple to be dead silent when I'm notin the boost. When I daily drove the car (going way back), I only heard the Whipple when passing or getting onto on-ramps.

It is silent until the bov closes. but it is very loud after that.

The paxton isn't as affected by a restriction after the blower as the whipple would be with a restriction before the blower.
I'm assuming this is a lower compression built motor? Get a frpp 62mm throttle body. I have swapped my throttle bodies several times for other reasons and even at 10psi, the difference is quite noticeable.
Not to take anything away from the centris, but the whipple will last longer IMO. Centris and turbos are cheap for a reason.

I expected it to be over 500 hp on the mustang dyno and near 600 on the dynojet, but after checking everthing I could, I took it to fastlane motorsport. and let them look it over, and I still have not found the problem.

Here's a post with videos of people running centris with BOV's.

My whipple is also dead silent until about 20% throttle. I have to put my ear to the blower at idle to hear the screws turning. That's what I don't like about prochargers, they sound like **** at idle.
